Niger is a Sahelian country located in West Africa, characterized by unfavorable climatic conditions, with low rainfall and continuous degradation. The combination of all these phenomena it is in this context that this study was carried out in the Aneker area. The study objective is therefore to make an exhaustive diagnosis of the irrigation and drainage networks. The methods adopted includes the study of hydraulic works of irrigation and drainage canals of the study area and supplement with interview of the stakeholders in irrigation, National Hydro-Agricultural Office (ONAHA) Technicians and those responsible for irrigation water management. The study reveals that 68% of the plots lack sufficient irrigation water. Remove the highlighted and replace with above sentence. Also, the results indicated that 91 % of irrigation farmers abandoned their plots of land due to lack of water from the severe degraded state of the irrigation water distribution channels. The 37% severely degraded state of the irrigation network leads to a huge loss in the transport of water to the plots. Consequently non-compliance with the water flow, the irrigation farmers are no longer able to have the water supply required to satisfy water needs. Which requires a longer irrigation time beyond 12 hours. So that the Aneker perimeter can be operational in an effective and sustainable manner, it would be interesting to rehabilitate all that remains of the hydraulic works. The limit of this research of irrigators in the maintenance of these infrastructures and in water management.
